This is a Phase 1/2A study designed to evaluate the safety and tolerability of increased repeated doses of LYC-55716 in subjects with locally advanced or metastatic solid tumors.

Drug: LYC-55716

Phase 1Phase 2

Detailed Description:

Approximately 30 subjects across approximately 5 United States (US) sites will be enrolled in the Phase 1 portion of the study and approximately 69-84 subjects across approximately 15 US sites will be enrolled in the Phase 2A portion of the study.

The Phase 1 portion of the study will follow a 3 + 3 dose-escalation design to evaluate twice-daily (BID) administration of LYC-55716 for DLTs and to determine the MTD and the RP2D for further assessment in Phase 2A. A treatment cycle will consist of 28 days of treatment and subjects may continue to receive subsequent cycles of therapy as long as they do not have clinically significant progressive disease.

In the Phase 2A portion of the study, 69-84 subjects with locally advanced or metastatic solid tumors considered most likely to be responsive to a RORγ agonist will be enrolled and treated at the MTD or RP2D.

Criteria

Inclusion Criteria:

Subject is male or female and at least 18 years of age.

Histological or cytological confirmation of advanced unresectable solid tumors, including those subjects who have progressed on standard anticancer therapy and for whom no further therapy that confers clinical benefit is available.

Subject has received an investigational drug in the 28 day period before the first dose of study drug (or within 5 half-lives if longer) or is currently participating in another interventional clinical trial.

Subject has known symptomatic brain metastases or leptomeningeal involvement as assessed by CT scan or MRI. Subjects with stable asymptomatic brain metastases or leptomeningeal disease are eligible if they have not required new treatments for this disease in a 28 day period before the first dose of study drug, and anticonvulsants and steroids have not been administered for a period of 2 weeks prior to the first dose of study drug.

Subject has not recovered from adverse reactions to prior cancer treatment or procedures (surgery, chemotherapy, immunotherapy, radiation therapy) to Common Terminology Criteria for Adverse Events (CTCAE) Grade 2 or better.

Subject has a previous (within 5 years) or current malignancy other than the target cancer with the exception of curatively treated local tumors such as carcinoma in situ of the breast or cervix, basal or squamous cell carcinoma of the skin, or prostate cancer with Gleason Grade < 6 and prostate-specific antigen within normal range.
